What physical factors control the rate of chemical reactions?
Surface area of the reactant.
The folded inner membrane in mitochondria which increases surface area for chemical reactions to take place is called what?
Cristae
Why is powder in a chemical reaction used instead of lumps?
Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.
What are four ways that chemists control the rates of chemical reactions?
Increase in Surface area,Increase in temperature,Increase in concentration,and the presence of catalysts or inhibitors.
What is a factor that speeds up chemical reactions beside catalyst?
Temperature - this is almost always the case. Pressure - this mostly applies to gases Concentration Surface Area
How is surface area important?
Surface area affects several things, such as how quickly an object cools down; the rate of chemical reactions will also depend on the exposed area.

What slows down chemical reactions?
It is called an inhibitor. surface area
What physical factors control the rate of chemical reactions?
Surface area of the reactant.
How does surface area work?
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
Why do Cells have convolutions?
The are convoluted to increase the amount of surface area that is available for chemical reactions and other interactions.
Why surface area important?
All chemical reactions take place on surfaces = so very important
The folded inner membrane in mitochondria which increases surface area for chemical reactions to take place is called what?
Cristae
Why is powder in a chemical reaction used instead of lumps?
Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.
Why is surface area to volume ratio an important concept in science?
Chemical reactions take place where the differeny chemicals come into contact - at their surfaces. Chemical reactions (including biochemical ones) are essential for our existence.
How does surface area to volume ration influence cell size?
Surface size directly affects the possibility for gas exchange. Volume affects how much the cell can contain. If a cell has a large volume and a small surface area, it will be able to keep in water easily. But if it needs outside gas input for its reactions, the small surface area may be a limiting factor.
Does mechanical breakdown increase speed of chemical breakdown?
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
